Why does a small dome light drain a huge car battery over night, yet a couple of AAAs can power a significantly more powerful, non-LED headlamp for days?
A car starter motor takes a lot of power. It has to turn over the engine enough times to cycle every piston and try to start each spark plug firing properly. You can leave a light on in your car for a day or two, but it'll drain the battery down too much to have enough power to turn the engine over.
The Short Answer
A car starter motor takes a lot of power. It has to turn over the engine enough times to cycle every piston and try to start each spark plug firing properly. You can leave a light on in your car for a day or two, but it'll drain the battery down too much to have enough power to turn the engine over. Plus you have to remember that cars use old incandescent bulbs, and that's many times the power requirement of an LED. Plus think how big an area a car light can illuminate.
